Stab Injuries

ObjectivesTo describe the epidemiology of assaults resulting in stab injuries among young people. We hypothesised that there are specific patterns and risk factors for injury in different age groups.DesignEleven-year retrospective cohort study.SettingUrban major trauma centre in the UK.Participants1824 patients under the age of 25 years presenting to hospital after a stab injury resulting from assault.OutcomesIncident timings and locations were obtained from ambulance service records and triangulated with prospectively collected demographic and injury characteristics recorded in our hospital trauma registry. We used geospatial mapping of individual incidents to investigate the relationships between demographic characteristics and incident timing and location.ResultsThe majority of stabbings occurred in males from deprived communities, with a sharp increase in incidence between the ages of 14 and 18 years. With increasing age, injuries occurred progressively later in the day (r2=0.66, p<0.01) and were less frequent within 5 km of home (r2=0.59, p<0.01). Among children (age <16), a significant peak in injuries occurred between 16:00 and 18:00 hours, accounting for 22% (38/172) of injuries in this group compared with 11% (182/1652) of injuries in young adults. In children, stabbings occurred earlier on school days (hours from 08:00: 11.1 vs non-school day 13.7, p<0.01) and a greater proportion were within 5 km of home (90% vs non-school day 74%, p=0.02). Mapping individual incidents demonstrated that the spike in frequency in the late afternoon and early evening was attributable to incidents occurring on school days and close to home.ConclusionsAge, gender and deprivation status are potent influences on the risk of violent injury in young people. Stab injuries occur in characteristic temporal and geographical patterns according to age group, with the immediate after-school period associated with a spike in incident frequency in children. This represents an opportunity for targeted prevention strategies in this population.

Introduction: Temporal trends in CF survival from low-middle-income settings are poorly reported. We describe changes in CF survival after diagnosis over 40 years from a South African (SA) CF center. Methods: An observational cohort study of people diagnosed with CF from 1974 to 2019. Changes in age-specific mortality rates from the year 2000 (versus before 2000) were estimated using multivariable Poisson regression. Data were stratified by current age < or ≥ 10 years and models controlled for diagnosis age, sex, ethnicity, genotype, and P. aeruginosa (PA) infection. A second analysis explored association of mortality with weight and FEV1z-scores at age 5-8 years. Results: 288 people (52% male; 57% Caucasian; 44% p.Phe508del homozygous) were included (median diagnosis age 0.5 years: Q1,Q3: 0.2, 2.5); 58 (35%) died and 30 (10%) lost to follow-up. Among age >10 years, age-specific mortality from year 2000 was significantly lower (adjusted hazard ratio aHR: 0.14; 95% CI: 0.06,0.29; p<0.001), but not among age <10 years (aHR: 0.67; 95% CI: 0.28,1.64; p=0.383). In children <10 years, Caucasian ethnicity was associated with lower mortality (aHR 0.17; 95% CI 0.05,0.63), and time since first PA infection with higher mortality (aHR 1.31; 95% CI 1.01,1.68). Mortality was 7-fold higher if FEV1z was < -2.0 at age 5-8 years (aHR 7.64; 95% CI 2.58,22.59). Conclusion: Overall, CF survival has significantly improved in SA from year 2000 in people older than 10 years. However, increased risk of mortality persists in young non-Caucasian children, and with FEV1z<-2.0 at age 5-8 years.

IntroductionEnding preventable deaths of newborns and children under 5 will not be possible without evidence-based strategies addressing the health and care of low birthweight (LBW, <2.5 kg) infants. The majority of LBW infants are born in low- and middle-income countries (LMICs) and account for more than 60%–80% of newborn deaths. Feeding promotion tailored to meet the nutritional needs of LBW infants in LMICs may serve a crucial role in curbing newborn mortality rates and promoting growth. The Low Birthweight Infant Feeding Exploration (LIFE) study aims to establish foundational knowledge regarding optimal feeding options for LBW infants in low-resource settings throughout infancy.Methods and analysisLIFE is a formative, multisite, observational cohort study involving 12 study facilities in India, Malawi and Tanzania, and using a convergent parallel, mixed-methods design. We assess feeding patterns, growth indicators, morbidity, mortality, child development and health system inputs that facilitate or hinder care and survival of LBW infants.Ethics and disseminationThis study was approved by 11 ethics committees in India, Malawi, Tanzania and the USA. The results will be disseminated through peer-reviewed publications and presentations targeting the global and local research, clinical, programme implementation and policy communities.Trial registration numbersNCT04002908 and CTRI/2019/02/017475.
